Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dry electrostatic precipitators, and more specifically, to a dust interception device for dry electrostatic precipitators. Background Technology
[0002] A dry electrostatic precipitator is a device that charges dust particles in a dry flue gas environment through electrode discharge and uses an electric field to migrate the dust to the collecting electrodes for collection and removal.
[0003] Common cleaning methods for dry electrostatic precipitators include mechanical vibration, electromagnetic vibration, and acoustic cleaning.
[0004] However, these methods can easily cause dust to be stirred up or temporary backflow when removing dust from the surface of the collecting electrode. The backflowing dust is re-mixed into the airflow, which not only contaminates subsequent gas treatment processes but also increases the dust concentration at the outlet, thereby reducing dust removal efficiency. In addition, the secondary re-entrainment of dust and the random movement of uncollected dust in the electric field increase the number of collisions between dust and the plates and wires, thus accelerating the mechanical wear of the plates and wires. This not only shortens the service life of the equipment but may also damage the electric field structure and affect its normal operation. Therefore, a dust interception device for dry electrostatic precipitators is proposed to improve the existing problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dust interception device for dry electrostatic precipitators.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dry electrostatic precipitator dust interception device, comprising a first channel, a motor disposed on the side wall of the first channel, a reducer disposed at the output end of the motor, a rotating shaft disposed at the output end of the reducer, one end of the rotating shaft penetrating the side wall of the first channel and connected to the output end of the reducer, and a rotating plate disposed on the side wall of the rotating shaft; a second channel and a third channel are disposed at one end of the first channel, a first filter screen is disposed at the end of the second channel away from the first channel, and a second filter screen is disposed at the end of the third channel away from the first channel.
[0007] The present invention is further configured such that: a first support frame is provided on the side wall of the motor, and one end of the first support frame is connected to the side wall of the first channel.
[0008] The present invention is further configured such that: a second support frame is provided on the side wall of the first channel, and the end of the flipping shaft away from the reducer passes through the side wall of the first channel and is connected to the second support frame.
[0009] The present invention is further configured such that: the second channel and the third channel are stacked one on top of the other, the second channel and the third channel have the same shape, and the flipping shaft is located in the middle of one side of the second channel and the third channel.
[0010] The present invention is further configured such that: the shape of the flip plate is the same as that of the second channel, and the outer wall of the flip plate is in contact with the inner wall of the first channel.
[0011] The present invention is further configured such that the length of the first channel is greater than the width of the flip plate, and the first channel can accommodate the flip plate for flipping.
[0012] The present invention is further configured such that: the first filter screen has a first hole around its perimeter, and the second filter screen has a second hole around its perimeter.
[0013] In summary, this application includes at least one of the following beneficial technical effects: by driving a reducer with a motor to rotate the tilting shaft, the tilting plate accurately blocks the channel where the filter screen needs to be replaced, thereby achieving secondary interception of dust in the electrostatic precipitator. This design not only makes filter screen replacement convenient, but also improves dust removal efficiency, reduces maintenance time and costs, increases overall work efficiency, extends equipment lifespan, and ensures stable operation of the electrostatic precipitator.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0022] Please see Figures 1-5 The present invention provides the following technical solution:
[0023] Example 1, see Figures 1-5 A dry electrostatic precipitator dust interception device includes a first channel 1, a motor 2 is provided on the side wall of the first channel 1, a reducer 3 is provided at the output end of the motor 2, a rotating shaft 4 is provided at the output end of the reducer 3, one end of the rotating shaft 4 passes through the side wall of the first channel 1 and is connected to the output end of the reducer 3, and a rotating plate 5 is provided on the side wall of the rotating shaft 4.
[0024] The first channel 1 is provided with a second channel 6 and a third channel 7 at one end. The second channel 6 is provided with a first filter 8 at the end away from the first channel 1, and the third channel 7 is provided with a second filter 9 at the end away from the first channel 1.
[0025] Among them, motor 2 serves as the energy source, providing power to the entire system; reducer 3 acts as a speed reducer and torque increaser, ensuring the smooth rotation of the tilting shaft 4; the tilting shaft 4 drives the tilting plate 5 to rotate, and the tilting plate 5 rotates accordingly, thus flexibly changing the working position or direction to meet different operating requirements; the second channel 6 and the third channel 7 are respectively connected to the first channel 1, ensuring that gas can enter the second channel 6 or the third channel 7 from the first channel 1; the first filter screen 8 and the second filter screen 9 are used to filter the dust that the electrostatic precipitator has not removed, improving the gas purification effect.
[0026] When the interception device is activated, the tilting plate 5 is in the middle position, not obstructing the second channel 6 and the third channel 7. The dust-laden gas flows into the second channel 6 and the third channel 7 through the first channel 1, and the dust is filtered and intercepted by the first filter screen 8 and the second filter screen 9. If the first filter screen 8 or the second filter screen 9 has too much dust and the filtration effect has decreased, and it needs to be replaced, the motor 2 drives the reducer 3 to rotate the tilting shaft 4, so that the tilting plate 5 rotates to the channel where the filter screen needs to be replaced, blocking the corresponding channel for replacement. This design not only realizes the secondary interception of dust in the electrostatic precipitator, but also facilitates filter screen replacement, improving dust removal and working efficiency.
[0027] See Figures 1-5 Furthermore, a first support frame 11 is provided on the side wall of the motor 2, and one end of the first support frame 11 is connected to the side wall of the first channel 1.
[0028] The motor 2 is provided with a first support frame 11 on its side wall, which supports the motor 2 and ensures the stability and reliability of the motor 2 in the equipment. One end of the first support frame 11 is connected to the side wall of the first channel 1. This design helps to enhance the structural stability of the first support frame 11 and ensures that the relative position between the motor 2 and the first channel 1 is fixed, thus avoiding unnecessary displacement or vibration of the motor 2 during operation.
[0029] See Figures 1-5 Furthermore, a second support frame 12 is provided on the side wall of the first channel 1, and the end of the flip shaft 4 away from the reducer 3 passes through the side wall of the first channel 1 and is connected to the second support frame 12.
[0030] The second support frame 12 is used to support the flipping shaft 4, ensuring that the flipping action is carried out under stable support, thereby improving the safety and operating efficiency of the equipment.
[0031] See Figures 1-5 Furthermore, the second channel 6 and the third channel 7 are stacked one on top of the other, and the second channel 6 and the third channel 7 have the same shape. The flipping shaft 4 is located in the middle of one side of the second channel 6 and the third channel 7.
[0032] The flipping shaft 4 is located in the middle of one side of the second channel 6 and the third channel 7. Its main function is to ensure that the flipping plate 5 can completely cover the second channel 6 or the third channel 7, and to avoid the flipping plate 5 not covering completely or getting stuck with the first channel 1 due to the unreasonable position of the flipping shaft 4.
[0033] See Figures 1-5 Furthermore, the shape of the flip plate 5 is the same as that of the second channel 6, and the outer wall of the flip plate 5 is in contact with the inner wall of the first channel 1.
[0034] The function of the flip plate 5 is to block the gas containing dust when replacing the first filter screen 8 or the second filter screen 9, so as to prevent dust from overflowing. The outer wall of the flip plate 5 fits tightly against the inner wall of the first channel 1, which further enhances the effect of preventing dust from overflowing.
[0035] See Figures 1-5 Furthermore, the length of the first channel 1 is greater than the width of the flip plate 5, and the first channel 1 can accommodate the flip plate 5 for flipping.
[0036] The first channel 1 provides sufficient space for the flipping plate 5 to flip, and its length is greater than the width of the flipping plate 5 to ensure that there is no jamming during the flipping.
[0037] See Figures 1-5 Furthermore, the first filter screen 8 has a first hole 81 around its perimeter, and the second filter screen 9 has a second hole 91 around its perimeter.
[0038] The first filter screen 8 is fixed in the installation position through the first holes 81 opened around its perimeter, so that it can withstand the mechanical stress of the exhaust gas flow and ensure the stability of the filter screen during use. The second filter screen 9 is also fixed through the second holes 91 opened around its perimeter, which increases its robustness and structural stability.
[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
